every time i click to create the msgBox() about 9MB of memory is piled onto IE. at first, i thought it might be the contents inside the <div> weren't being destroyed properly, but when i set up the function to just display the <div> by itself - i got the same issue.

any ideas on what can be done, if anything, in IE to fix this problem? typically this wouldn't be an issue, but my users are going to be opening up these transparent boxes often and the memory will add up quick.

i appreciate the response. i've read that codeproject.com article before thinking that maybe i wasn't clearing out the elements properly, but after this latest test of just displaying a simple <div> with a style attached i've found out that it's the filter style in CSS for IE that's causing the memory pile-up.
